We publish below a selection of the songs and music tracks that were used either in the final full-length version of the film, or in on of the two preceding 'trailers' released in 2009 and 2010. Thank you to all Guatemalan musicians and groups and others who contributed material / gave us the rights to use their material.

'El Eco del Dolor' (The Echo of Pain) was written in Manchester by Honduran musician and filmmaker Gerardo Martínez when he was here working with Lucía Cuevas on the editing of the film. Gerardo then sent a copy of the music to his mate, Chico XX, who added the second instrumental track in Honduras, before returning it to Gerardo for multi-tracking the vocals for the final audio mix.

Josh Lorenz created a lot of possible musical background tracks for the film, many of which we used as they seemed to fit in very subtlety with the visuals, rhythm and 'tone' of the film, enhancing the content without being 'over dramatic.' His advice on technical issues around post-production sound were invaluable.
